Dr. Warren received a bachelor of science degree in chemical engineering from Cornell University in 2005 and a master of philosophy degree in engineering for sustainable development from the University of Cambridge in 2006. She completed her Ph.D. at Caltech, studying the growth and energy conversion properties of Si microwire arrays as well as the electrochemical characterization of semiconductor photocathodes and catalysts for solar fuel generation. At NREL, Warren is researching the heteroepitaxial growth of III-V semiconductors on Si substrates, nanoimprint lithography, and developing electrodeposited contacts for high-efficiency Si solar cells. Her other research interests include the photoelectrochemical characterization of new semiconductor materials and solar thermoelectric generators.
